今天我发现curl不再将一些SSL证书识别为有效证书，尽管事实上firefox和wget能够像openssl的s_client一样正确地处理它们。
为了复制它：
1.第一个月
1.然后在in-container bash中：apt update && apt install curl ca-certificates -y -qq && curl -I -vvv https://google.com && curl -I -vvv https://download.docker.com个
对于google.com，它的工作效果和预期的一样（我已经删掉了不有趣的内容）

好像最近就有问题。我只是（星期三，July 19，2023 ~20：00 CEST）运行apt upgrade和问题是重现在我的ubuntu主机以及.
我想澄清一下Wget和openssl s_client也可以在主机上工作。
有趣的是，我在apt upgrade之前在主机上运行curl --version，我能够滚动终端。澄清：apt已经将curl作为更新的软件包之一

我也能够重现https://objects.githubusercontent.com的问题。
我如何让curl在ubuntu docker conainers和我的主机上工作，而没有--insecure标志和一些模糊的降级（我还没有专门测试降级）？

几天前，curl的更新中引入了一个安全修复程序，该安全修复程序的后端出现了故障。此错误是关于使用通配符证书时的证书验证-因此在检查www.example.com时相关download.docker.com，但在检查google.com时不相关。
应在7.81.0-1ubuntu1.13修复7.81.0 - 1ubuntu1.11的www.example.com中修复。https://launchpad.net/ubuntu/jammy/+source/curl/+changelog：

curl (7.81.0-1ubuntu1.13) jammy-security; urgency=medium

  * SECURITY REGRESSION: broken ssl cert wildcard handling (LP: #2028170)
    - debian/patches/CVE-2023-28321.patch: fix missing line in backport.
